The good news this heating of earth has happen before.? Last time was around 1905 it did get very cold in 1944. We have not broken any records from 1905. It is not ever x number of years it has to

Possibly. But my running time may not produce the kind of dangerous heating that we think. I do mostly small stuff. My motor is also a brushless one.? george

Nope. Just a remodeled two car garage without insulation. No ac, just a small fan. Today at my house it was 114. george

It more likely to do with air compressor sitting outside for shop air. The mini lathe should be in a cooler room. Maybe the AC keeping the you mini lathe and you cool Dave

Intermittent operation may actually make the motor internals hotter than continuous running! With intermittent running, the motor's internal fan is stopped while the heat generated internally is still

I do at times but it's never long running stuff. A bit here and there. So I seriously doubt there would be any issues doing it that way. And it's not often. For sure I do more in the upper 80s so i

Here calculations for mini lathe in ambient temperature 104°F? [40°C] Motor rize in temperature 60°C Hot spot 5°C Total is 105°C Then check your insulation temperature along below you good

Using a mini lathe and other tools in 2004 most of time temperature of 105°F and maybe spikes to 108°. Today the temperature is over 108° and days to 113°F So odds of burning the mini lathe motor

A few months I add a temperature gauge to my lathe and the Calc on how down does a mini lathe motor gets. If go on internet you all garbage formulas on this subject for just few degrees.? But

Gerald you are right about Global Warming you can easily debunk it with a little research it is only making someone very rich.

This is gradually turning Into a discussion of politics which, some of us will remember, is what destroyed the 7x10 minilathe group. Let's not go down that road. Mike

While acknowledging that there are natural cycles of the earth heating and cooling, we also have to look at what drives feedback for those systems, and perhaps several of the changes made by man, such

We feel humidity as making the heat worse because our bodies are cooled by evaporation. humidity slows down the evaporation process. But this does not apply to motors. The more modern way to use

Most motors have? ambient temperature of 105°F [40°C] Now live a hotter location a reduced in horse power. Here simple clip on motors . It max winding temperature you watch for. If look on

Haven't heard that name in a while...

And now you also know one of the reasons why motors used in the lunar and Mars rovers, and in similar applications require so much engineering. When there is no atmosphere, you are left with only

??? ??? Good thing we don't have too many Simon Bar Sinister's around? . animal

??? ??? just saw that yesterday? , haven't given it a full read yet . ??? animal

Yeah, we went around and around on this a while back. The concept of “it’s the melting point of the enamel on the motor coils” that sets the temperature limit seems to have escaped Dave.

And if anyone isn’t aware, brushes have different hardness grades. The trade off is soft brushes need replacing more often but don’t wear the commutator, and the opposite for hard ones. Of
